PHASED ARRAY INSPECTION

Thai NDT Indonesia offers fully code compliant Phased Array Ultrasonic Testing (PAUT) as a replacement to on-site radiography.

Developments in construction codes have allowed PAUT to be used as a direct replacement to Radiography on piping butt welds to meet the quality control requirements of ASME B31.3 and B31.1 and numerous European standards.

PAUT can be worked towards both workmanship and Engineer Critical Assessment (ECA) acceptance criteria, with data being suitable for accurate sizing and defect characterization.

PAUT enables reduced inspection time by simultaneously collecting multiple angle ultrasonic data in a one pass scan from either side of the weld. Typical inspection rates are between 15-20 butts per shift.

By ensuring accurate scan plans and specifically designed techniques all construction defects are readily detected, sized and sentenced accordingly.

UT (ULTRASONIC TEST)

Ultrasonic methods of NDT use beams of mechanical waves (vibrations) of short wavelength and high frequency, transmitted from a small probe in contact with the specimen surface and detected by the same or other probes.

Such mechanical vibrations have dierent forms depending on the direction of particle movement in the wave motion, so there are several forms of ultrasonic waves. The most common and widely used in NDT are compressional and transverse (shear) waves.

MT (MAGNETIC TEST)

Magnetic Test (MT) is a nondestructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such asiron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization.

Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material.

Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current which may be either alternating current (AC) or some form of direct.

PT (PENETRANT TEST)

Penetrant Test (PT), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).

RT (RADIOGRAPHY TEST)

A well established NDT technique, radiography uses gamma-rays or X- rays to produce the image of an object onto film. The source of radiation is either an X-ray tube, which is normally described by the electrical voltage across the X-ray tube with the higher the voltage the higher the penetrating power of the radiation or a sealed source of radioactive material emitting gamma-rays: Iridium 192,
Cobalt 60, Selenium 75, Ytterbium 169.

Applications include wall loss detection and sizing in pipes and plate through to manufacturing defects in welds, forgings castings etc.
